Answers

Answer 1

Answer:

Answer:

option d 10/4

Step-by-step explanation:

by dividing 10 by 4 you get 2.5 which is a decimal

Answer 2

Answer:

Whole numbers

A whole number is a number that is either positive or zero. Fractions are not included. Some examples of whole numbers are 2, 3, 0, 122, but not 2/3.

So let's take a look at all the given options :

⇒ 10/2 (it simplifies to 5, so it's a whole number)

⇒ 0/5 (it simplifies to 0, so it's also a whole number)

⇒ 6/3 (it simplifies to 2, which is a whole number)

⇒ 10/4 (it simplifies to 5/2, which is not a whole number)

Therrefore our answer is d) 10/4

The vertex form of the equation of a parabola is x = (y - 4)2 + 27. What is the standard form of the equation?

A. x = y2 + 8y + 27
B. x = 4y2 - 8y + 43
C. x = y2 - 8y + 43
D. x = y2 + y + 15

Answers

Answer:

Option C. x = y² - 8y + 43

Step-by-step explanation:

The vertex form of the equation of a parabola is x = (y - 4)² + 27

We have to find the standard form of the equation which is in the form of x = ay² + by + c

To get the standard form of the equation we will simplify the vertex form of the equation.

x = (y - 4)² + 27

x = y² + 16 - 8y + 27

x = y² - 8y + 43

This matches with option C. x = y² - 8y + 43

Since the vertex formula of an equation is x =a(x-h)^2 + k and the standard form of an equation is y = ax^2 + bx + c, the answer to the math question presented above would be letter c. x = y^2 -8y + 43. I arrived to this answer by solving (y-4)^2 and adding the equation to 27.

Find the volume of a sphere with a radius of 6 cm. Approximate 2004-06-01-05-as 3.14 and round your answer to the nearest hundredth.

Answers

Given:
Radius = 6 cm

Volume of a sphere = 4/3 * π * r³

V = 4/3 * 3.14 * (6cm)³
V = 1.33 * 3.14 * 216cm³

V = 902.06 cm³

Answer:

C. 904.32

How to solve linear equations by substitution?

5x+2y=9
x+y=-3

Answers

5x+2y=9 x+y=3

change x+y=3 into x=3-y

plug that equation into 5x+2y=9 where x is.

5(3-y)+2y=9

then distribute.

15-5y+2y=9

15-7y=9

minus 15.

-7y=-6

divide both sides by -7.

y is equal to -6/7.

then go back to the first equation and plug in for y.

and then you will get x.

then you will have (y,x)

$\begin{cases} 5x+2y=9 \n x+y=-3\end{cases} \n \n\begin{cases} 5x+2*(-3-x)=9 \n y=-3 -x\end{cases} \n \n\begin{cases} 5x-6-2x =9 \n y=-3 -x\end{cases}\n \n\begin{cases} 3x =9+6 \n y=-3 -x\end{cases}$

$\begin{cases} 3x =15 \ \ /:3 \n y=-3 -x\end{cases} \n \n\begin{cases} x =5 \n y=-3 -5\end{cases} \n \n\begin{cases} x =5 \n y=-8\end{cases}$
